WIRE-STRETCHER.

Specification of Letters Patent.

Patented July 11, 1916.

Application filed October 31, 1914. Serial No. 869,648.

To all whom it may concern:

Be it known that I, CHARLES W. BARTLEY,

a citizen of the United States, residing at Erie, in the county ofVVhiteside and State of Illinois, have invented new and usefulImprovements in WVire-Stretchers, of which the following is aspecification.

The present invention relates to improvements in devices for stretchingw1re fences, and resides in the construction, combination andarrangement of parts set forth in the following specification andfalling within the scope of the appended claim.

In the drawing: Figure 1 is a view illustrating my improvement inoperative position, Fig. 2 is a longitudinal sectional view on the line2-2 of Fig. 1, and Fig. 3 is a vertical sectional view on the line 3-3.of Fig. 1.

Referring now to the drawing in detail, the numeral 1 designates anordinary woven wire fence, 2 vertical clamping bars which are secured tothe fence in order to permit of the said fence being stretched andattached to a post 3. The bars 2 have yokes 4 surrounding the same andarranged to the opposite ends thereof, the said yokes being providedwith eyes 5 for the reception of the end links of chains 7. These chainshave their inner end links secured to an eye 8 which is swiveled uponone end of a longitudinally extending threaded rod 8. The rod 8 passesthrough an opening 9 provided in what I will term a head 10. This head10 preferably comprises a rectangular member, and has attached adjacentthe opposite ends thereof chain members 11 and 12, each of which havingtheir end links provided with a hook 13, and each of the chains isadapted to be wound around a post 14 to bring their hooks 13 between oneof the links of each of the said chains.

The head 10 has, what I will term, its outer face, provided with anannular depression 15 which surrounds its opening 9, and which isadapted to serve as a bearing for a nut member 16. The nut 16 includes arounded body, having a threaded bore which co-acts with the threads ofthe rod 8, and the portion of the body next to that received within theannular depression 15 is formed upon its outer perimeter with an annulardepression or slot 17, blocks 18 having their lnner edges provided withsemi-circular depressions being received within the groove 17, andconnected with the head 10 through the medium of bolts 19.

The nut or member 16 has its outer face provided with a second annulardepression 20 which is adapted to receive the semi-cylindrical portionsprovided upon the members comprising a head 21 for a lever 22. Theportion of the nut 16 beyond its groove 20 is formed with teeth 23, andthe head 21 has pivotally connected therewith a doubleheaded pawl 23.This pawl may, of course, be swung to bring either of its engagingportions between the teeth 23, so the lever 22 may be manipulated toturn the nut 16 in two directions, to draw the threaded rod 8 toward thehead or permit of the said rod being moved toward the fence and'clamp.

Preferably integrally formed with the nut 16 is a handwheel 2 1, whichmay be employed when it is not convenient to operate the lever 22 orwhen only a slight adjustment of the threaded bar Sis required.

From the above description, taken in connection with the accompanyingdrawing, the simplicity of the device, as well as the advantages thereofwill, it is thought, be perfectly apparent to those skilled in the artto which such invention appertains without further detailed description.v

Having thus described the invention, what I claim is:

A wire stretcher including a threaded rod, a head having an openingthrough which the rod passes, said head having its inner face providedwith an annular depression which surrounds the opening, a grooved nuthaving a rounded perimeter received within the recess, removable meansmounted within the groove of the nut and contacting with one face of therounded perimeter and connected with the head and cooperating with therod for sustaining the nut upon the head rotatable with respect to thelatter, said nut receiving the rod and cooperating with the threadsthereof, a lever including a head arranged for rotation upon the nut,the nut being provided with teeth, a dog having two engaging facespivoted to the head and In testimony whereof I affiX my signatureadapted to engage between the teeth of the in presence of two witnesses.

nut for im oartin rotar movement to said nut, and a hand wheel formedcontiguous CHARLES BARTLEY' with the free end of the nut for impartingWVitnesses:

a further rotary movement to the nut inde- L. A. MATTHEWS,
